The Checker Framework

The Checker Framework is an open-source tool that enhances the Java programming language with a powerful type system to detect and prevent runtime errors such as null pointer exceptions, concurrency issues, and SQL injections. It provides compiler plug-ins that automatically verify code correctness or allow developers to create custom checks for specific bug patterns. Widely used in both academic research and industry applications, it includes supporting utilities like inference tools and dataflow analysis frameworks.
